Aerox problems? Please help!

[Baxendale]

Hey guys, I'm a newbie here as you can probably tell My names Shaun and I ride a Yamaha Aerox (you've got to start somewhere huh!)

Anyways, I bought my Aerox in February ready for my birthday next month (July) and just recently it's all been going wrong. It was running fine but now it seems to keep on flooding. I start it and it runs for a minute then cuts out So I check my spark plug and it's totally pee'd up so I clean it all up and put it back in and yes, first kick, it starts. Runs for another minute then cuts out, check the spark plug, flooded again! Around 2 weeks ago my brother's friend said it could be the carb floats so he gave the side of the carb a few tap's, i started it and yes it ran for the few minutes that I had it started! I went back to it 2 days later, the problem was back again and here I still am today stuck with the problem. I have opened the bottom of the carb up and moved the float up and down and it worked again for the 2 minutes that it was running but now again a few days later it is broke, AGAIN!.. with the same problem.

Someone said down jet, obviously not due to the fact that it was running fine.. even I know that and I'm no bike mechanic People are still saying carb float sticking, how can it be if I moved it around like I've been told to?

Please help me out guys, I'm a skint teenager who has his CBT in 18 days!

Many thanks

ok im presuming you have not been riding it, just idling in youre garage or something. This may be part of the problem. Once you're going along and revving through the range, then it will work better me thinks.

Although, check the spark plug gap.
Tap the float bowl a bit and run it up and rev it quite a lot with centrestand down. See if it works ok.

Okay mate, i'll try it out tomorrow and let ya know how I get on.

Cheers for ya help

Crappy fuel? How long has the fuel been in the tank? I will assume it's been there since February. Try changing it and see how long it runs for.

As Allymoss said, it may just need a good ride.

if you take off the float bowl, could u take a picture at where the main jet is as i would like to see were abouts it is and how hard it is to take off please

the main jet is just a screw with a hole it. To remove, just take the float bowl off and unscrew with correct size flat head screwdriver.

That was probably his main jet lmao.. simple enough to remove, just unscrew the 2 screws on the bottom of the carb..

Didn't try my ped today, I left my keys in my dads car and he was at work Yeeeh im dumb but I'll let you all know as soon as I've tried it..

And yeah, about 50p's worth of fuel has been in there since feb but the other £4's worth has only been in there a few weeks..

Cheers

I had a ped ages before my CBT and used to just mess on with it lol.

i honestly think it could be the fuel. I did the same thing, was in my garage for ages and before my CBT i wanted it MOT-ing. So my dad went to take it and the thing was doing the same as yours!

I put some new fuel in and my dad took it out straight away. He had the thing flat out for ages and when it came back the whole thing sounded better, had a smoother tick over and pulled away much better.

As you have newish fuel what you need to do is start it, then get on it and just hammer it. Do this for a good 15mins and then it should be fine

Oh you havent been cleaning the air filter by any chances? Just i did that and put to much oil on the foam filter. I also used 2 stroke oil lmao It did a similar thing. I just had to clean it again and put air filter oil on, which i learnt is so much thinner lmao.

Ok, tried it today and now it starts for roughly 3 seconds. I took my exhaust off because its blowing due to me snapping a stud in the manifold and also the bolt that is in doesn't even fit properly. but anyways, i took it off and it had a small extra round bit on the end of the exhaust where it goes into the manifold (possibly the restrictor?) so i took it off as it was stopping me from bolting the exhaust into the manifold flush, put it back on with a gasket and put the old bolt on again (the one thats too big - cant find another one).. anyways, still sounds the same and still doing the same thing, running for 3 seconds then cuts out..

i started it just now and when i revved it it's really weak and you can clearly tell its going to cut out..

anyone know whats up with it?

my mate said clean the air filter out?

god knows lol.. CBT in 14 days, god I hope it's running in time!

[Baxendale]

Cleaned air filter out, no change..

Anyone think it may well be the spark plug? is it worth getting a new one or is it not that?

Cheers.

Had a simmilar problem with my aerox
Ended up changing the ht lead and ignition coil.
That along with the fact the fuel was crap didnt help. Running it in for hundred or so miles helped me

Tenths of a mile?

And (just an idea) why not start new threads instead of restarting prehistoric ones?
